from which it is presumably intended to be inferred that certain lines of neon are ordinarily present in the vacuum tube spectrum of hydrogen. A further examination of the observational data ...

A NUMBER OF scientists and academics are sounding the alarm about California’s plans to implement passenger rail trains that ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

MANY examples of changes in ultra-violet absorption spectra attributable to hydrogen bonding have been reported and summarized by Ito 1. However, in few of these cases has the change in ...

Using hydrogen makes it possible to adjust heat levels across a broader range. It particularly allows coffee to be roasted for a long time over a very low flame, which natural gas cannot sustain ...
